OIL-SEPARATOR FOR STEAM AND WATER.

SPECIFICATION forming part of Letters Patent No. 338,772, dated March 30, 1886.

Application filed December 7, 1885. Serial No. 184,932.

(No model.)

Patented in Germany July 5, 1885, No. 34,090.

To all whom it may concern:

Be it known that I, EUGEN POLTE, of Magdeburg, Germany, have invented a new and Improved OilSeparator for Steam and \Vater, of which the following is a full, clear, and exact description.

It is well known that the water obtained by condensing steam from steam-engines, &c., contains considerable quantities of oil and grease, and consequently said water cannot be used for feeding boilers, and the oils and fats in the same are lost. The oils and fats in the exhaust-steam from engines, &c., are also lost.

The object of my invention is to provide a new and improved apparatus for separating said oils and fats from the water of condensation and from the exhaust-steam, so that said oils and fats can be used again.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out particularly in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a cross sectional elevation of my improved apparatus for collecting oils and fats from exhaust-steam. Figs. 2, 3, and 4 are cross-sections of modified construction.

The nozzle A is secured on the end of the exhaust-pipe B,and projects into a cylindrical sheetmetal casing, (J, in the top of which the outlet D is provided. In the casing C an up right perforated cylindrical casing, E, is held, in which a spiral track-plate, F, is provided, which throws the steam issuing from the nozzle A outward. At one side of the nozzle A a channel, G, is formed, which conducts the -water of condensation collected in the casing annular space between them, acting as an airjaccnt to prevent the cooling of the inner casing and the solidification of the oils and fats therein. In the upper part ofsaid cylinder Ia pan, K, is placed, which is formed on the upper part of a cylinder, K, on the broader base part 75 resting on the upper surface of the bottom of the cylinder 1. An outlet-pipe, L, for water, extends up through the bottom of the cylinder I and through the space between said cylinder and the cylinder K. A tube, M, is screwed on the lower end of the plug J and into the bottom of the cylinder 1, and is provided with a series of slots, 3 A sliding tube, 0, is contained within the tube M, and is provided at its lower end with a handle, 0, through which the lower end of the tube 0 passes, and to which it is secured.

The operation is as follows: The steam issuing from the nozzle A strikes the spiral track F and is given a rotary motion, throwing out Water and oil, which is condensed to a certain extent. The greater part of the fats and oils are condensed and run down through the channel G with some of the water into the pan K. The annular ridges J on the plug J prevent the steam from passing freely into the cylinder 1 and disturbing the surface of the oil and water. The oil remains in the cylinder K, and the water passes through a pipe, P, up into the space between the cylinders K and I, and then flows off through the outletpipe L. \Vhen the oil is to be withdrawn, the pipe 0 is pulled down a greater or less distance, and the oil and grease that have collected on the top of the water within the cylinder K pass through the slots M and into the upper end of the tube 0, and then run down through said tube. The oil and water that condense in the nozzle A pass through the branch tube A into the neck G.

In the device shown in Fig. 2 the exhaustpipe B is also provided with a nozzle, A, which is in the casing or cylinder Q, to the lower end of which the cylindrical casing R is attached, down into which the tube R projects from the casing R. R is the outlet-nozzle for the oil in the tube R, and R" is the outlet-pipe for the water.

In the construction shown in Fig. 3 the pipe A projects through the top of the vessel B down towithin a short distance from the bottom of said vessel B and near the top of the vessel B the pipe A is provided with the spout G which projects over the open top of the vessel D" in the vessel 13*, the said vessel D being provided at its lower end with the outlet-cock 1 which is below the bottom of the vessel B The tube E projects upward from the bottom of the vessel B, and has its lower end connected with the water-outlet pipe F and in the bottom of the said tube E a seat is formed for the valve G2 on the lower end of the rod H in the tube E", 011 the upper end of which rod the float J is secured. A semicircular plate, K is held inclined in the pipe A in the top of the vessel B", to prevent agitation of the water in the vessel B, so that the oil and fats can separate perfectly from the water. The oil collects on the top of the water in the pipe A-, on account of the different specific gravity of water and oil, and flows through the spout G into the vessel D", from which it can be drawn at suitable intervals.

through the cock 1*. As the water rises in the vessel B it raises the valve G, and the water can then flow off through the pipe F.

In the construction shown in Fig. 4 the two pipes -W and V are secured on a casing, X,

y and the steam is conducted to the top of the pipe V, which has a funnel in its upper end, to prevent agitation of the water, and is also provided at its upper end with an outlet-nozzle, WV. The oil flows oli' through said outletnozz'le, and the clean water flows through the outlet-pipe V in the pipe V.

Havingthus described myinvention, I claim as new and desire to secure by Letters Patentl. The combination, with a vessel divided into two compartments in communication with each other at their'lower ends, of an outlet for each compartment, and of a float-valvev for closing the outlet of one of the compartments, substantially as herein set forth. 7

2. In an apparatus for separating oils and fats from water, the combination,with a steamnozzle, of a cylindrical vessel held below the same. which nozzle is provided with a channel for conducting the water of condensation and oil into the cylindrical vessel below it, and of an outlet-pipe for the water in the cylindrical vessel, which outlet-pipe extends up to the levelof the water in said cylindrical vessel, substantially as herein shown and described.

3. In an apparatus for separating fats and oils from water, the combination, with a steamnozzle, of a cylindrical vessel held below the same, into which vessel the water of condensation, fats, &c., are conducted, an outlet-pipe for the water in said cylindrical vessel, which outlet-pipe extends from the bottom up to the desired level of the water in said vessel, and

of a sliding outlet-pipe within said cylindrical vessel, substantially as herein shown and described.

4:. In anapparatus for separating fats and oils from water, the combination, with a steamnozzle, of a cylindrical vessel held below the same, into which vessel the water of condensation, oils, fats, 8m, can be conducted, an annular partition dividing the cylindrical vessel into two compartments, a water outlet pipe in one compartment, a slot-ted pipe extending through the othercompartment, and a sliding oil-outlet pipe in said slotted pipe, substantially as herein shown and described.
